Reference excerpt

Linda Karen Medlin is a molecular biologist known for her work on diatoms. She is an elected member of the Norwegian Academy of Science and Letters.

Education and career Medlin has a B.S. from the University of Texas at Austin (1970), and an M.S. (1977) and a Ph.D.(1983) from Texas A&M University. She has worked at the Alfred-Wegener-Institute in Germany (1991-2009), Observatoire océanologique de Banyuls-sur-Mer in France (2009-2013), and the company Microbia Environment in France (2013-2016). From 2008-2025, she was an associate research fellow at the Marine Biological Association. She presently holds two honorary professorships.

Research Medlin's early work was with Greta Fryxell on the taxonomy of diatoms. She is known for her work on applying molecular tools to the study of phytoplankton, and she was the first to develop primers for polymerase chain reaction that targeted eukaryotic organisms, She applied this tool to taxonomic studies of multiple species of phytoplankton cultured in the laboratory. Her work extended into the ocean where she examined the diversity of phytoplankton in different regions including the Pacific Ocean, Antarctica, and the time series from the German research station at Heligoland. Through the application of molecular tools, Medlin was able to define species differences in coccolithophores and examine the evolution of diatoms. In 2007, Medlin led the group who discovered a new lineage within photosynthetic eukaryotic organisms, the picobiliphytes, and then presented the first cultured strain in 2013 but the group is not photosynthetic but heterotrophic and feeds primarily on cryptomonads and may keep their plastids, hence the chartarcteristic pigments first associated with the group. More recently. Medlin has worked on the phytoplankton within harmful algal blooms and improving methods for monitoring such blooms using DNA barcodes as probes in electrochemical biosensors.

Awards and honors Medlin was elected foreign member of Norwegian Academy of Science and Letters in 1998. Four of Medlin's papers have received awards, one paper received the Luigi Provasoli award from the Phycological Society of America, and three papers have received the Tyge Christensen Award from the International Phycological Society. Medlin received the Yasumoto Lifetime Achievement Award from the International Society for the Study of Harmful Algae in 2021.

Worked examples

Example 1 — a first encounter with Linda Medlin

Start with the simplest possible case. Write down what Linda Medlin claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Linda Medlin before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Linda Medlin ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Linda Medlin

In research: Linda Medlin appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Linda Medlin in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Linda Medlin is common in secondary-school and first-year university syllabi. It links to neighbouring topics American botanists, American women botanists, Living people, so understanding it makes those chapters shorter.
In everyday life: Look for Linda Medlin outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
